The Irwin Speedbor maximum speed wood drilling bit is the fastest Speedbor ever. The speed tip features a full screw-point that allows bit to self-feed, as well as three (3) cutting spurs for faster, cleaner holes, less breakout and extended drilling life. The tapered tri-flute design allows for faster chip ejection and less binding. Its grooved Hex shank prevents slipping and fits all standard 1/4 inch quick-change chucks, including impact drills.
